wild boars. Sea animals Whale engravings are in general 20 to 30 cm long and between 10 and 80 cm high. Most show whales swimming in a group upward as if seen from a bird's-eye view. Sideway engravings of whales are made in a "twisted method" in which the tail is carved sideways to show the horizontal tail of the whale, which is different from fish. Other rock art shows a mother whale with her baby on her back, whale jumping scenes, and large cetaceans migrating to and from the remote sea, all vividly depicting whale behaviour. The whale horizontally overturning a boat with its body seems to be dead, and stripes carved on its body are thought to be distribution or breakup lines, resembling ethnographic material describing natives distributing pieces of whale. These engravings are assessed to provide important information about the hunting and subsequent distribution of large animals. The three turtles on the upper left of the main rock face appear to be guiding whales swimming in a group. Since sea turtles come to the shore to spawn between early spring and summer, they are often regarded in ancient myth as symbolic animals crossing the boundary of sea and land. In the case of fish, heads of fish looking like sharks are depicted sideways, and there are salmon jumping above the sea surface. On later engravings there is the suggestion of a wooden fence, but since the inner outlines resemble fish and land animals are lacking the possibility of a fishpound has been considered. Land animals Most of the land animals are shown in a side view, which can best express the shape of four-limbed land animals. Some species can be classified according to the shape of body, skin patterns, the length of tail and legs, and the shoulder line. These include sika deer, red deer, musk deer, roe deer, and water deer. Sea birds are always placed around whales as they are hunting prey. Some engravings show mating and molt scenes of land animals and because of different patterns and angle of fall suggest the annual change of seasons and the breeding season. Tools Tools relating to hunting and fishing such as boats, floats, harpoons, fishing net, fish pounds, and bows provide information on the age of the rock art and livelihood of the time.
